Auxiliary braking device in engine cylinder, braking method and road roller
The invention discloses an auxiliary braking device in an engine cylinder, a braking method and a road roller. The device comprises a pressing plate, a bidirectional electromagnet and a piston arranged in a piston cylinder, the top end of the piston cylinder is provided with an intake valve and an exhaust valve, and an exhaust passage where the exhaust valve is located is provided with an exhaust stop valve; the bidirectional electromagnet is connected to the bottom face of the pressing plate, a check block is connected to the output end of the bidirectional electromagnet, and the bidirectional electromagnet is used for controlling the check block to be located at a first position or a second position; at the first position, the check block stretches out to prevent a rocker arm from returning so that the exhaust valve can be opened; and at the second position, the stop block retracts, and the rocker arm returns to close the exhaust valve. According to the auxiliary braking device in the engine cylinder, the braking method and the road roller, in-cylinder braking can be well achieved, the braking pressure of a drive axle is relieved, and the safe driving performance of the road roller is improved; and the structure is simple and reliable, and measures such as engine oil pressure are not needed.
本发明公开了一种发动机缸内辅助制动装置、制动方法及压路机，该装置包括压板、双向电磁铁和设置在活塞缸内的活塞，活塞缸的顶端设有进气门和排气门，排气门所在的排气道上设有排气截阀；双向电磁铁连接在压板的底面，双向电磁铁的输出端连接有挡块，双向电磁铁用于控制挡块处于第一位置或第二位置，在第一位置，挡块伸出，阻碍摇臂回位以使排气门打开；在第二位置，挡块缩回，摇臂回位以使排气门关闭；本申请可很好的实现缸内制动，减轻驱动桥制动压力，提升压路机安全驾驶性能；而且该结构简单可靠，不需要借助机油压力等措施。
